This paper describes a user interface developed to input by moving a terminal device. First, the concept of the portable viewer with a magnifying glass-like operation already proposed and the remaining problems are described. Next, a new method of detecting the device movement using optical flow is proposed. Then, a prototype built with an embedded 32-bit MPU to verify the proposed method is outlined...
This paper describes a contact-free input method which does not use a pointing device. The proposed device has an input function to capture the user's palm motions and an output function which displays a screen directed by the palm motions. First, a miniature camera captures the palm motions and inputs the images. Next, a color conversion appropriate for palms, and wrinkle detection by thinning and...
This paper describes a method of correcting the velocity vector by using the characteristics of the wrinkles in palms for hand gesture input for remote controllers. First, the HSV color system is used for hand images because this color system is not affected by changes in the lighting conditions. Next, an input method by switching the referenced parameters used for recognition when the range of acquisition...
